I expected that around 10,000 people would have a perfect score in the class given my experience with Asian participation in online programming contests. There are a few countries in that part of the world where organizing a group to check each others' work and ensuring perfect scores is common and encouraged even when the official requirement is to do your own work. And those happen to be countries filled with millions of smart people. India, China, and Russia seem to be the heart of the phenomenon. Google, Facebook, and Topcoder have systems to deal with it but ai-class.org does not.
Anyway I'm neither surprised nor disappointed not to be in the top sliver. I'm not hireable anyway. It's funny that there is an identifiable top 1,000 at all instead of 10k+ perfect scores.
I.E., it would make sense they only want to hire people under certain age, or certain academic enrollment status... Who knows...
How do you know this?
